Is _member_name an ACF field?

In the actual ACF module, it’s “member_name” not “_member_name”, but yes it is.

There is a “member_name” in the dropdown though, good call.

Did that fix it? Each custom field in ACF uses 3 meta keys, only of of which (the one you just found) has the data. If you try to search on any meta key those without a value will disappear from the cache.

Interesting. I won’t know if it’s fixed until tonight (when whatever cron or refresh runs that’s actually causing the cache to wipe out), but I’ll be keeping an eye on it. That sounds right though, I’ll update any progress.

Looks like that didn’t do it. Emptied out again this morning.

Ah. I see that you use WP Engine, which gives me an idea.

There is a setting to override a feature of WP Engine hosting, that truncates long SQL queries (which ours are). Edit the site wp-config.php file and add this at the top, after line 1 (on a new line 2):

define('WPE_GOVERNOR', false);

(also see here for another related support note about this – https://support.searchandfilter.com/forums/topic/killed-query-errors-in-log/#post-64826)

I would just say though, that rather than adding this in blindly, to research and make sure this setting doesn’t adversely affect anything in your site.
